Try Nav-TV.com I have been told they can make your factory Nav unit accept DVD's and play them at any speed. They currently advertise this for Cayenne. It does require that you ship your factory Nav unit to them for mods. I have NOT done this but this company seems to be well known within their industry. Good Luck
